Abstract: When molding surfaces (50A) of a pair of dies (50) are to be cleaned by air-blowing, air is blown towards the molding surfaces (50A) from blowing nozzles (22A) of a cleaning blowing function portion (22) while a moving body (16) is reciprocatingly moved by driving force of a driving mechanism (18). When a parting agent is to be applied to the molding surfaces (50A) of the pair of dies (50), the mold release agent is jetted out towards the molding surfaces (50A) from spraying nozzles (24A) of a parting agent application function portion (24) while the moving body (16) is reciprocatingly moved by the driving force of the driving mechanism (18). In both of these situations, at the same time as the treatment of the molding surfaces (50A), a cleaning brush (32) reciprocatingly moves together with the moving body (16) and sweeps a device floor surface (12).

Abstract: An object is to accurately estimate loss-on-ignition in a short time. A loss-on-ignition estimation apparatus includes at least one processor configured to carry out an estimation step, the estimation step including estimating the loss-on-ignition of foundry sand with use of a learned model constructed by means of machine learning. The learned model is configured to receive, as input, (1) sand weight data relating to a weight of the foundry sand detected in a calcination period and (2) at least one of (i) sand property data relating to one or more properties of the foundry sand, (ii) additive data relating to one or more additives added to the foundry sand, and (iii) calcination environment data relating to a calcination environment detected in the calcination period. The learned model is configured to generate, as output, an estimated loss-on-ignition of the foundry sand.

Abstract: An operation device receives an operation which an operator has carried out in order to move an operation target. The operation device includes an operation section, a first member, a second member, and a force sensor. The operation section is capable of being subjected to one or both of a tilting operation and a rotating operation. The first member is mechanically connected to the operation section and is displaced in accordance with an amount of operation by the operation section. The second member stops the first member at a predetermined stop position. The force sensor detects, while the second member is stopping the first member, a force or moment which is applied to the second member.
